Mostly, this is true. There are plenty of abilities that were added in wotlk that were necessary though. Hex was a needed spell at the time as well as lava burst. With the wotlk changes, elemental shamans would not have done any damage without lava burst, nor would they have had any form of cc without hex. Adding spells can be good, but it's extremely reliant on the metagame and whatnot. That's for another thread though.

Rocket boots in arena made s5 too fun. . . if you had them of course

I think an example of a good spell addition would alter time, because it has so many uses/possibilities. It can be used offensive or defensive and overall increases the skill cap of a mage. But unfortunately the majority of spells added just end up being one dimensional that you have to use to be competitive.. Like frostbomb, all it is is another ability that just does damage when mages had a perfectly fine system of doing damage before. I think the same comparison could be made for avatar vs bladestorm(when it was useful). It was an ability that could be used offensively or defensively, and could be be countered, where as avatar is just another cooldown that has no real utility other than increasing your damage.
edit: I think I'm picturing bladestorm around s7-s8.

Just because it has many uses, doesn't mean it's a good addition. People are going to disagree because rogues suck right now, but smoke bomb is easily one of the worst additions to this game, and it has MANY uses.

Expect bias in posts because
Wotlk is the best thing since sliced bread

I don't understand how anyone finds CD stacking and random one shots fun. i'll take an incredibly imbalanced s5 over s12 any day. i'm not looking through rose-colored glasses here. pvp in this game has progressively become worse and worse. there are high points and low points mixed around, but each new expansion brings an entirely new design system that detracts from good play and encourages a one dimensional play-style.

TBC: build pressure and keep pressure to win by coordinating cc's, most of which have a cast time.
wotlk: like TBC, only faster paced with higher burst/dmg and healing, some op instant abilities.
cata: fairly high dmg, healing eventually sucks by s10-11. train healer into the ground. game-breaking instants and interrupts for all.
mop: dmg is pathetic, unless you pop 2-3 3 minute cds to blow someone up in a few globals. healing is op.

my opinion? if they took a mixture of tbc and wotlk the game would be as good as it can be. minor tweaks to class balance. this is a business though, so the more blizzard fucks up everything the better for them because it makes it look "new and exciting" when really it's just "different" and often times "worse" from a pvp perspective.

Why can't people wrap their heads around the fact that things change? The biggest problem with the pvp community is the amount of nostalgia they experience and how it more or less ruins their perspective of every new expansion. There's obvious broken mechanics in the game, but can you not say the same for literally every other season? Let's take the time to enjoy the game for what it is instead of complaining about what it could be.

it's not what it "could be." it's what it has been.

nobody expects perfection, but when it progressively becomes worse it is legitimate thing to be upset about, even if we have no control over it

I see things in a completely different light then you, why exactly should you get upset over something you admittedly have no control over?

it's not that anyone should get upset. i am saying that pvp has gotten worse. just because "things change" doesnt mean they are always good change and people who are upset or just simply dissapointed with the direction the game has gone have every right to

Obviously it's all relative and people have different perceptions but to me, s5 was the worst season that could ever be. I see many threads where people miss wotlk so much, it was so fun and balanced etc. It's clear that wotlk kept a few classes very happy and it was fun for them but it was a horrible expansion for many others.
In wotlk, broken things either never got fixed or it took Blizzard seasons to make the necessary changes: Here is a list, that comes to my mind(I probably missed many other things here):
-Undisarmable bladestorm, unrelenting assault, undispellable innervate/divine plea, prot/holy paladin, death knights, destro lock, elemental shaman, armor penetration, caster haste, shadowmourne, dfo, tnt stun etc.

Now look at MoP, they fixed hunters already; mages , shamans and warriors are getting nerfs and it's just the first patch, where as in wotlk, they let things go for many seasons.
Like I said, this is all relative to one's class/what classes partners played, but I feel like no expansion can ever go as wrong as wotlk.
